Abstract: The average cluster method( UPGMA) was used to analyze the horizontal distribution of Ardisia plants in the cities or counties of Hainan Island. As a result,the central region of Hainan Island is the most abundant area for Ardisia,especially in Baoting County. The vertical distribution of Ardisia was concentrated in the altitudes ranging from 400 to 1 000 m,and 7 species were distributed narrowly. Ardisia was distributed in two types and two subtypes,but mainly in the subtype from Vietnam( or Indo-Chinese Peninsula) to S. China( or SW. China),followed by the type of Endemic to China. The Ardisia plants in Hainan Island had close relationships with those in the neighboring provinces Guangdong and Guangxi,the most similar to those in Guangdong and the most common with those in Guangxi. The Ardisia plants in Hainan Island had significant relation with those in the neighboring area of Indo-Chinese peninsula,but not obvious relation with those in Malaysia.
